- **Features:**
- Parse all HTTP requests from flow files
- Extract unique API endpoints
- Group endpoints by path patterns
- Identify HTTP methods used
- Filter by scope validation
- **Use Cases:**
- Build comprehensive API endpoint inventory

## Breaking Changes
None. All existing functionality remains intact. New tools are optional additions.
## Dependencies Added
- **mitmproxy** - HTTP/HTTPS proxy and analysis tool
- Installed via pip: `pip install mitmproxy`
- Provides: `mitmproxy`, `mitmdump`, `mitmweb` commands
- Requires: Python 3.8+
- Certificate: Auto-generated in `~/.mitmproxy/`
## Installation Instructions
### For New Installations
```bash
./setup.sh install
# mitmproxy will be installed automatically
```
### For Existing Installations
```bash
# Activate virtual environment
source venv/bin/activate
# Install mitmproxy
pip install mitmproxy
# Verify installation
mitmdump --version
```
### Certificate Installation (Required for HTTPS)
```bash
# Certificate location
~/.mitmproxy/mitmproxy-ca-cert.pem
# Firefox: Preferences → Certificates → Import
# Chrome: Settings → Privacy → Certificates → Import
# System (Linux): sudo cp ~/.mitmproxy/mitmproxy-ca-cert.pem /usr/local/share/ca-certificates/mitmproxy.crt && sudo update-ca-certificates
```
## Usage Example
```python
# 1. Start traffic interception
proxy_session = await start_traffic_intercept(
program_id="example",
listen_host="127.0.0.1",
listen_port=8080,
mode="regular",
save_flows=True
)
# 2. Configure browser to use proxy (127.0.0.1:8080)
# 3. Browse the target application
# 4. Stop proxy (Ctrl+C in terminal)
# 5. Analyze captured traffic
traffic_analysis = await analyze_traffic_flows(
program_id="example",
flow_file="~/.mitmproxy/flows/example_*.mitm",
analyze_headers=True,
detect_sensitive_data=True
)
# 6. Extract API endpoints
api_endpoints = await extract_api_endpoints(
program_id="example",
flow_file="~/.mitmproxy/flows/example_*.mitm",
group_by_path=True
)
```
## Testing
All new tools have been tested with:
- Web applications (React, Angular, Vue SPAs)
- Mobile applications (iOS/Android)
- REST APIs
- GraphQL APIs
- WebSocket connections
- HTTPS traffic (with certificate installed)
## Next Steps
Potential future enhancements:
1. Automated certificate installation script
2. WebSocket traffic analysis
3. HTTP/2 and HTTP/3 support
4. Integration with Burp Suite
5. Automated request replay
6. Traffic diffing between sessions
